mzscheme package missing "scheme" collection

[Dan Cecile]

I just installed DrScheme and I'd like to start writing some programs. The basic DrScheme tutorials suggest using the "scheme" language, but when I try, it says,

standard-module-name-resolver: collection not found: "scheme" in any of: (#<path:/home/dancecile/.plt-scheme/372/collects> #<path:/usr/lib/plt/collects>)

In the /usr/lib/plt/collects directory, I only have the following collection folders:

afm algol60 big browser combinator-parser compiler config defaults doc drscheme dynext embedded-gui eopl errortrace ffi framework frtime games graphics help hierlist htdch htdp html icons info-domain lang launcher lazy macro-debugger make mred mrlib mzlib mzscheme mztake net openssl parser-tools planet plot preprocessor profj profjWizard r5rs readline scribble setup sgl slatex slideshow srfi stepper string-constantsswindle syntax syntax-color teachpack test-box-recovery tests tex2page texpict trace version web-server wxme xml

I think the package has an issue because the "scheme" folder is there in the Ubuntu self-extracting script from the DrScheme website.
